| Abstract: | A new design scheme of hand-held power harmonic analyzer based on LabVIEW DSP(Digital Signal Processor) module is presented.It takes a 32-bit floating-point DSP as the core and completes real-time acquisition of currents and voltages with less hardware such as sensors and the A / D converter.While the quasi-synchronous sampling,digital filtering,adding windows,FFT(Fast Fourier Transform) operation,electric parameter calculation and so on,are implemented by software in DSP.It makes full use of LabVIEW DSP module in interaction,usability,integrated resource and data processing ability,thus making the development easier and faster.The designed analyzer is of multi-function,small cubage,high-performance and easy expansion. |
